Eleven adults and six kids at the California park were struck by flying poop, according to the Anaheim Police Department.

Disneyland officials then called the fire department, a police spokesperson told BuzzFeed News, in order "to determine what the material was."

Don't worry: the poo-spray wasn't the result of a scared person riding a roller coaster. It appears that birds, specifically geese, were responsible for the traveling turds. (It's still unclear what the motive was).

BuzzFeed News understands the Hazmat call went out to fire officials because in the darkness it wasn't immediately clear what the smelly substance was.

The pooped-on people were taken to a private washroom and offered fresh clothing.
